What is login on Mac?
login · seed · quit hint: caution
login is a macOS process — also matched as com.apple.login. People usually find it in Activity Monitor when asking “what is this process?”
What does login do?
login authenticates a user (via PAM) and starts their login session, often as the parent of a shell or terminal session. Terminals, remote login services, and session tools invoke it. Quitting ends that login session and its child shell—do not kill active logins you still need.

Is it safe to quit login?
Hint: caution. SystemWoe Free and Pro use keep-guards so you don’t blindly kill something important — Pro adds force-terminate only with confirmation.
